Answer :

Final answer:

Add 6 to both sides of the equation x - 6 = 9, which gives us the equation x = 9 + 6. Solve the right side to get x = 15.

Explanation:

The question asks to solve for

x

in the equation x - 6 = 9. To do this, we can use the principle of algebra that, to maintain equilibrium, what you do on one side, you must do on the other. Given the equation x - 6 = 9, to isolate x on one side, you just have to add 6 to both sides, which makes the equation x = 9 + 6. Calculating the right side gives us x = 15. So, the solution to the equation x - 6 = 9 is

x = 15
